2、分布及噪声特性,综合吸声、隔声、消声、阻尼减振、通风和泄压等技术,采用半密闭式降噪厂房和阻抗复合排气消声器等治理措施。治理后厂界噪声从64.2~72.1dB(A)降至49.7~55.0dB(A),距厂房最近厂界25Hz声压值从97.9dB降至84.2dB,排气消声器出口噪声从84.3dB(A)降至72.6dB(A)且25Hz声压值从124.7dB降至97dB。厂界噪声达到GB12348—2008《工业企业厂界环境噪声排放标准》3类要求,中、低频噪声强度减弱,解决了厂界噪声超标和噪声扰民问题。同时,为整体式天然气压缩机组噪声治理开辟了一条新途径,为日后降噪厂房和阻抗
3、复合排气消声器广泛应用奠定了实践基础,为压缩机组噪声治理设计积累了宝贵经验。关键词声学;天然气压缩机组;噪声治理;通风散热;防爆泄压中图分类号:TB53文献标志码:ANoiseControlMeasuresinHuang⁃geCompressionStation121XUJun,HUANGDe⁃bin,MENGYi⁃rong(1.ChongqingKehuaEnvironmentalEngineeringCo.Ltd,Chongqing400030,China;2.ChongqingDesign&ResearchInstitute,ChinaCoalTechnol
